Specify the behavior of a Simulink S-function when saving and restoring the operating point of a model containing the S-function
void ssSetOperatingPointCompliance(S, setting)
SSimStruct representing an S-function block.
settingDefine how to treat an S-function simulation state when saving and restoring the model simulation state. Permissible values are:
OPERATING_POINT_COMPLIANCE_UNKNOWN (default
value)
USE_DEFAULT_OPERATING_POINT
USE_EMPTY_OPERATING_POINT
DISALLOW_OPERATING_POINT
USE_CUSTOM_OPERATING_POINT
ssSetOperatingPointCompliance allows you to specify how
Simulink® should treat an S-function during a save and restore of the model
simulation snapshot (ModelOperatingPoint).
If the S-function does not specify its
OperatingPointCompliance, then Simulink assumes the OPERATING_POINT_COMPLIANCE_UNKNOWN
setting. This setting instructs Simulink to issue a warning and then switch to
USE_DEFAULT_OPERATING_POINT in lieu of the
OPERATING_POINT_COMPLIANCE_UNKNOWN.
If the option is set to OP_COMPLIANCE_DEFAULT and if the
S-function does not use PWorks, then Simulink treats the S-function like a built-in block. Simulink saves and
restores the same data as the operating point (for example continuous states,
non-scratch DWork vectors, and zero crossing signal information), as it would for a
built-in block. If S-function has Pworks, not setting compliance results in an error
on saving operating point. Use custom compliance,
USE_CUSTOM_OPERATING_POINT, to save data in Pworks.
C, C++
Use the ssSetOperatingPointCompliance function to specify the
simulation state compliance of an S-function in the
mdlInitializeSizes method. The specification is based on the
first character vector parameter value.
static void mdlInitializeSizes(SimStruct* S)
{
ssSetNumSFcnParams(S, 2); /* two parameters */
if (ssGetNumSFcnParams(S) != ssGetSFcnParamsCount(S))
return;
ssSetSFcnParamTunable(S, 0, false);
ssSetSFcnParamTunable(S, 1, false);
{
boolean_T visibility = 0U;
ssSimStateCompliance setting =
GetSimSnapParameterSetting(S, &visibility);
if (ssGetErrorStatus(S)) return;
ssSetOperatingPointCompliance(S, setting);
ssSetOperatingPointVisibility(S, visibility);
